the depositor. The shaft 1 carriesa sprocket 4 and a rotating arm 5. Theshaft is driven through the medium of a gear 6 of the required'diameter,and which may derive its power from the filling machine, not entirelyshown. The gear (5 meshes with the gear 7 on the shaft 1. The salter ordepositor comprises a base 8, which is supported by the bars 9, which inturn may be supported in any suitable manner,possibly at 10, on theframe 11 of a filling "The depositor also comprisesthreetelescopical-members or shafts 12, 13 and 14, the first one being solidthroughout with its upper I end'at 15 carrying an agitator 16, while itslower end carries a sprocket 17 about which a chain 18engages, thelatter receiving power from the sprocket 4 on the shaft 1. The agitatorconsists of a spider 19 with a plurality of depending arms or rods 20,which extend into and terminate atithe bottom of a hopper 21 of thedepositor or salter'. Thelower eX tremities of the arms or rods 20 carryresilient agitator blades 22, for scraping the interior of the hopperand thereby agitating the salt or other substance to be deposited.

The hopper 21 is mounted upon the plate 8, and maybe any shape and ofapproved ype r r The shaft 13 is hollow and the solid shaft- 12 passesthrough it, while the shaft 14 is hollow and telescopes the shaft 13exteriorally. The lower end of the shaft 13 carries a disc 23 having aplurality of teeth 24, there being four in number at diametricallyopposite p oints, so that an intermittent movement may be imparted tothe disc and a corre- V sponding movement to the shaft 13, for thepurpose of actuating a plate 25 on the interior of the hopper at thebottom thereof. The agitator spring plates 22 ride over this plate 25,and thereby not only act to scrape the salt or'otherpulverized substancefrom the face of the plate, but also from the side of, the hopper,especially near the bottom thereof. Rising from the plate 25 is a cone 726 rotating with the plate and this cone also spring agitating blades22.

Referring to Figure 1 of the drawings it will be noted that the hopper21 has a flat perpendicular wall, especially at the location near wherethe salt or other pulverized substance is discharged or deposited. Thefiat 7 wall is positioned a substantial distance in toward the centralcone 26, sufficiently to permit the disc forming openings 27 to passexteriorly of the hopper, that'is beyond the flat perpendicular wall 28of the hopper, thereby permitting the plunger head 29 of the plunger rod30 to pass through each of the openings 27 as they pass beyond the walland register with an opening 31 in the plate 8. The plunger rod isguided in a bearing 32 of an arm 33, which is bolted or otherwisesecured at 34 to the plate 8. 'Fixed on the plunger rod 30 is a collar35 by means of a set-screw 36, and above and below the col lar insurrounding relation to the plunger rod 30 are coiled springs 37 and 38,the former being of greater tension than the latter, so as to providequick action for the plunger rod when the plunger head 29 is inthe actof passing through the registering openings 27 and 31.

Alsorising from and secured to the plate 8 as at 39 is an upright 40having an opening 41 through which a bar 42 is guided. The

upper lateral end of the bar 42 slidably carries the plunger rod 30,said rod being held in'position in the extremity of the lateral arm bymeans of a set bolt 43, the spring 37 acting between the collar 35 andthe extremity ofthe lateralarm of the bar 42.

V The lower end of the bar 42 passes through the plate 40 and carries ananti-frictional roller 44, with which a cam 45 engages for actuating thebar 42 in a downward direction, and since it carries the plunger rod 30,the plunger head 29 is depressed by a spring 37 underaction of the bar42 against 25, as in Figure 7, so that it will snap into the opening 27when in registry with the opening 31.

It is obvious that by adjusting the collar 35 upwardly on the plungerrod 30, the greater distance the plunger head 29 will pass through theregistrating openings 27 and 31. By adjusting the collar 35 downwardlyon the plunger rod 30 the less distance the plunger head 29 will passthrough the registering openings 27 and 31.

The cam 45 is mounted upon an intermittent oscillating arm 46, which iscarried by the upper end of the exterior shaft or'sleeve 14, the lowerend of whichin turn carries a disc 47 secured in position by a set screwor 7 bolt 48; I

. Pivoted .tothe disc 47 by means of a pin 49 is a link or bar 50, whichin turn'is pivoted on a pin 51 of the arm 5 on the lower end of theshaft 1. Obviouslythe shaft 1 of the if filling machine, not shown,receives acontlnuous rotary motlon, and due to the arm 5 being carriedthereby, 1t rotates 1n a corre-' spending direction, hence imparting arecip- I rocatory motion to the bar or link50. fThe bar or link 50 beingpivoted to the plate or disc- 47, 1 imparts an intermittent movementbackwards and forwards to the disc or plate 47 ,and hence imparts, acorrespondingmove- -ment to the sleeve or shaft .14. Obviously aboutwhen the opening 27 is registering with the opening 31, the cam 45 isjust in the act of engaging with the roller 44, hence starting the bar42 on a downward movement against the action of the spring 38 (which isinterposed between the collar and the bear-.

ing 32), the spring 371acting-to overcome the tension of the spring 38and depressing the plunger head 29 due to the action of the bar 42against 25 as in Figure7, so that it will snap with quick action intothe opening 27 when in registry with opening 31. The entering of theplunger head in the regis tering openings 27 and 31 is accomplished whenthe cam has moved the. arm 42 sufli I ciently, and the plate-or disc 23has been r0 tated sufiiciently to carry the plate 25 far, enough tocause a registering of the openings 27 and 31. A pawl 52 is pivotallymounted at 53 on an arm 54 which is carried by the plate or disc 47 andthis pawl .52 is'spring tensioned through the medium of a leaf spring55. The pawl 52 is designed to engage with any one of the severalnotches or teeth 56 of the disc or plate 23, hence imparting a rotatingmovement to the disc orplate 23 intermittently. At the end of eachintermittent motion of the plate or disc 23, one of the openings 27registers with the opening 31, and as this registering action takesplacenecessary to increase the sizeof'the plate 25 and possibly make theopening larger in diameter, though not necessarily; I I

Regular tests and experiments have shown that this salter will operateaccurately,

whether the salt or other seasoning be dry, damp or even wet.Experiments have shown that better results are attained where the salt Iis damp.

Also carried by thearm 46 is anangular guarding cam 57, which positionsbelow the roller 44 asthe plunger head descends in order to enter theregistering openings '27 and 31; In Figure 5 the plate 25 is shown assubstantially thicker than that in Figure 3,.showing it possible to so,increase the size of the plate as to provide for-forming discs j of saltor other substance of increased thickness.

In the 7 operation the cans "containing tomatoes are passed under theregistering openings 27 and 31 through the medium of the table orrotating disc2, and as they pass under the openings the seasoning suchassalt or the l1ke 1s measured in disc form and conveyed exteriorally ofthe hopper,;that is beyond the flat perpendicular portion 28 of thehopper, then the plunger descends and forces'the discv of salt fromtheopenings 27 and 31" into each individual can; .Inthisopa;v eration theplate 25, the plunger head 29 and its rod and the cams 45 and 57receivepoWer or are operated by the shaft 1, due to the individualoperativeconnections between the shaft 1,the sprocket 17, the disc 23and the disc or plate 47.
